IPC: F16C33/10
Filed: 1994-01-17
Abstract: PURPOSE:To provide a sufficient shaft rigidity at a low cost by composing a shaft and a bearing of nonmagnetic and magnetic members, respectively, and providing a permanent magnet having a magnetic area crossing the rotational direction, at part of bearing. CONSTITUTION:A radial bearing 4 is composed of magnetic body, and a plurality of parmanent magnets 24 of wedge type are formed at the inner face of the bearing 4. Between the bearing 4 and a shaft of nonmagnetic material magnetic fluid is filled in, and it is attracted to the side of bearing 4 by the magnetic field generating in the permanent magnet 24. At a face opposite to a thrust stator 1 or a stepped part of thrust stator 1 of the shaft 5, a plurality of parmanent magnets 24 having magnetic areas 23 are formed. The magnetic fluid filled in the bearing 4 is attracted to the permanent magnet 24 formed on both thrust and radial bearing faces 4 and fluid is pushed to the central part of any bearing, thereby requiring no special seal for retaining magnetic fluid in the bearing part 4 completely.

Title: Manufacturing method of wing-shaped blade
Inventor: AMANO YOSHIAKI
IPC: B21D26/033
Filed: 1979-01-17
Abstract: PURPOSE: To manufacture a highly precise wing-shaped blade in a very simple process by pressing down a hollow pipe into a flat shape by means of a mold with a perpendicular force to the axis of the pipe while giving an oil pressure inside the pipe.  
     CONSTITUTION: A pipe material 4 is inserted between an upper and a lower metallic mold 3 and 3', and an oil pressure inside is opplied thereto. Then, the upper metallic mold is put down to transform the pipe. At this stage, the pipe material 4 is stuck tightly to the inside of the mold by virtue of the oil pressure inside to be shaped into a wing-shaped blade 1. The oil inside the pipe is returned to an oil pressure device 6 by a portion equivalent to the displaced amount of the pipe. In this illustration, the width of the metallic mold is equal to the length of the blade to be manufactured, and shown by l. The pipe material 4 is continuous and long. Therefore, when the position of the metallic molds is shifted, for instance, from A to B B to repeat the above process, a number of wing-shaped blade can be manufactured successively.

Title: Detector
Inventor: SAKURAI ISAO
IPC: G01V8/16
Filed: 1979-01-16
Abstract: PURPOSE:To secure the simple detection for the presence or absence of the fluid according to the variation of the refractive index which is caused by the existence of the detected fluid featuring the fixed refractive index at the interface part where the light entered from one end of the 1st optical conductor is transmitted to the 2nd optical conductor. CONSTITUTION:When the light given from the light source is put in through one end 14 of 1st optical conductor 1, the light travels within core component 11 with repetition of reflection on the interface between conductor 1 and coated layer 12 to be radiated into the space of inner part 42 of tube 4 from end face 13. The radiated light is scattered outside after transmitting through tube 4. As a result, an extremely small amount of the light reaches the end face of 2nd optical conductor 2. When space 42 of tube 4 is filled with the water, the light is refracted by the water and goes toward incident end 23 of conductor 2 to be put into core component 21. Thus the presence or absence of the water can be detected based on the volume of the light put into component 21.

Title: Production of zn-fe alloy electroplated steel sheet
Inventor: SUZUKI NOBUKAZU
IPC: C25D5/48
Filed: 1983-01-13
Abstract: PURPOSE:To prevent the burning by acid on the non-plating surface of a steel strip and to improve chemical convertibility in the stage of subjecting one surface of the steel strip to plating by electroplating a Zn-Fe alloy on the inlet side of a plating line on the other surface then passing the steel strip in a non-conducting state through the plating soln. CONSTITUTION:A Zn-Fe alloy is electroplated on the other surface of a steel strip as well on the inlet side of a plating line to form a protective film in the stage of subjecting one surface of the steel strip to the intended Zn-Fe alloy electroplating. When the other surface of the steel strip is thereafter passed through the plating state in a non-conducting state, the Zn-component in the above-described protective film is preferentially dissolved and the protective film is enriched with Fe. If the time when the strip passes in the plating soln. in the non-conducting state is suitably selected, the Fe-component in the protective film is made adequate on the outlet side of the plating line. The burning by acid on the other side, that is, non-plating surface is thus prevented and chemical convertibility is improved. More particularly, the steel sheet which is plated on both sides in multiple layers at different thickness and have the corrosion preventive layer and the layer improved in the adhesion of the paint coated film is obtd.

Title: Measuring apparatus for determining angle of rotation
Inventor: KURAUSU DOPURAA
IPC: G01B7/00
Filed: 1991-01-17
Abstract: PURPOSE: To obtain a measuring apparatus which can operate conveniently over a wide frequency band while facilitating manufacture of a coil by arranging second members on the opposite end faces of a first member where corresponding cores are arranged with winding coils. CONSTITUTION: Cores 12, 13 constituting a coil body 11 have D-shaped cross-section and arranged on a holder 14. The cores 12, 13 are applied with winding coils 15, 16 and the measuring apparatus can be applied to a wide range of holder frequency range from 5kHz to 5MHz, for example, by simply varying the diameter and the number of turns of the winding. Semicircular discs 19, 20 movable relatively to the coil body 11 are arranged on the opposite end faces of the coil body 11 while being fixed to a shaft 18 and an AC field induced in the coils 15, 16 by an AC current induces eddy currents on the metal surface of the discs 19, 20. The discs 19, 20 are turned in parallel with the end face of the coil body 11 and the eddy current increases as the field surface penetrating the discs 19, 20 increases.  The eddy current varies the AC resistance of the coil and the variation is utilized for obtaining a measurement signal. Variation in the inductance of the coil is also utilized.

Title: Oscillation and acoustic detector
Inventor: HASHIMOTO TAKESHI
IPC: G01H1/00
Filed: 1990-01-11
Abstract: PURPOSE:To accurately detect oscillation or sounds emitted from an object by supporting a stylus on a holding tool, which is fixed to the object, through a buffer material and electrically converting the oscillation and sounds transmitted to the needle by a sensor. CONSTITUTION:The oscillation of a engine transmitted to a flange 6 is transmitted to a distortion sensor 2 through the stylus 1, and a voltage signal corresponding to the deformation of a diaphragm is outputted through a wiring 7. Prior to the detection, a holder 5 engaged spirally with the holding tool is rotated to advance the stylus 1 together with the sensor 2, and a locking nut 9 is tightened to control the rotation of the holder 5 when the front end of the stylus 1 comes into contact with the flange 6, and thereby, the stylus 1 is kept brought into contact with the flange 6 with the same pressure and the detection work is performed without supporting the stylus 1 with a hand. Since a sensor case 8 of the sensor 2 is supported through a buffering agent 3 made of silicone gel, the oscillation or the like of the engine transmitted from the flange 6 to the holding tool 4 is interrupted by the buffering material 3 and is not transmitted to the case 2. Thus, noiseless data of high quality is obtained.
